Accurate fetal skul detection for mesurements and diagnosis

The final result was to accurately measure cerebral gap, encephalitic pockets in the third ventricle and other critical measurements taken in a routine ultrasound test in end of second trimester. The measurements were extracted from a 3D scan of the fetal brain automatically locating the position, registration, correcting location and creating virtual slicing according to medical procedures.
